<p>A relational to object mapping system (12) and method permit the transfer and translation of data between a database server having a relational database and an object-oriented apparatus. The object code, such as C++, is translated by a generator object into suitable relational database statements, such as structured query language (SQL). The SQL statement is passed to a query object which executes the statement. In executing the SQL statement, the query object accesses an environment object (14) which supplies the query object with appropriate connection objects for establishing a link between the query object and the database server (20). The database server supplies the requested data from the relational database to the query object which then sotores the data in a storage buffer. The object-oriented apparatus can then access the data from the storage buffer.</p> |
